Recently (Oct 27th) me and a friend decided to start a gaming forum over at http://allforthegamers.com
2 weeks ago we set up an official minecraft server
we have about 100~110 users (friends, friends of friends, etc) and about 85~95 banned spam bot accounts that got to the forums through google crawling.
We're looking to grow and expand the community now, what are the best sites to pruchase advertising space on to get quality members (people who participate in the community) ?
